Answer:
In the following AP first three terms are -2 , 0 , 2
Step-by-step explanation:
In the given AP , first term is -2 and common difference is 2
a(n) = a + (n-1)d ; where
a(n) = nth term
a = first term
d = common difference
the second term is , a(2) = -2 + (2-1)×2 = -2 + 2 = 0
the third term is , a(3) = -2 + (3-1)×2 = -2 + 2×2 = -2 + 4 = 2
Hence the first three terms in the following AP are -2 , 0 , 2
